Condensate Return Pumps and Boiler Feed Units | Boiler Supplies

At Boilersupplies.com, our boiler feed and condensate return systems are designed to maintain peak efficiency and extend the life of your boilers, particularly when the investment in a deaerator cannot be justified. These systems consist of one or more feed and condensate return pumps and a receiver tank, available in carbon or stainless steel. They automatically supplement condensate with makeup water to replace system losses. In the boiler feed system, cold water is heated by mixing with hot condensate return and is pumped to the boiler on demand. We stock units with tanks ranging from 6 gallons to 500 gallons.

Features:

• Control Panel Options: Systems using three-phase motors can be supplied with a NEMA Type 1, 4, 12 control panel enclosure. These include magnetic starters, H-O-A selector switches, external resets, and, where required, standby selector switches. Dual units do not require a standby selector switch.
• Compatibility: Designed for use with scotch-marine and fire tube boilers at operating pressures up to 150 PSI. Suitable for locations requiring automatic unattended operation.
• Temperature Management: In industrial installations, condensing equipment on steam lines typically returns water at temperatures of 180˚ - 190˚F, while steam heating systems return water at about 160˚F. Chemical treatment of feedwater is introduced through bypass feeders or proportioning pumps to ensure that feedwater chemicals do not pass through the pump.

Pump Design:

• Cavitation Resistance: Engineered to resist cavitation, ensuring extended pump life and stable operation.
• Top-Mounted Pumps: Pumps are top-mounted on tanks to keep all mechanical seals above the waterline. A float switch automatically turns pumps on and off.
• Tank Specifications: Tanks are made of cast iron, with 2" NPT female intake connections, 1" NPT female discharge connections, and 1/2" NPT female drain connections. They feature open drip-proof (ODP), continuous duty, single-phase motors wired for 120 VAC, and have a junction box with screw terminals. Temperature range: 160° to 200°F. Made in the U.S.A.

Condensate Pumps:

• Functionality: Designed to collect condensed liquid at remote locations in a steam system and move it back to the boiler room. Condensate can be driven by either electricity or steam.
• Motor-Driven Units: Typically feature centrifugal type pumps with controls that de-energize the pump when the water level in the receiver is low. These units have a 3/16" thick welded steel or cast iron receiver and a close-coupled, bronze-fitted, centrifugal pump. Available in simplex and duplex configurations, with or without mounted, pre-wired control panels.
• Steam-Driven Units: Ideal for hazardous environments or locations where electricity may not be readily available.
